There's probably a better way: use the html canvas. I tried to implement a turtle module to be embedded with Crunchy (http://code.google.com/p/crunchy) - it is available as a demo experimental feature. You could use this as a starting point if you want. André

would it be difficult -- how do you think?

Hey, thats cute :) 1) I played around, and added Turtle.circle() to actions :) in code its called called circle_forward(self, radius, extent=None) and also aliased as circle you can find it http://files.akl.lt/users/jurgis/python/crunchy/ 1a) seems it would be best to use canvas interface methods, which are already in graphics module (according to DRY phylosophy) or at least decine upon method naming -- which just generate code vs those that pass it to exec_js plugin 1b) seems, like polygons and filling also would not be a big problem https://developer.mozilla.org/en/Canvas_tutorial/Drawing_shapes#section_9 for fill you'd just jave to collect the points and then repeat them with fill() at end 2) and also I'd like to make it convert all actions to javacript code at once then it would be easier to implement turtel_js and graphics in other projects -- easily escaping crunchy :D As now for asinchronous update, the server and session must be up all the time 2a) then probably time.sleep would be also good to interface directly to js something like http://groups.google.co.in/group/phpguru/browse_thread/thread/8215dcdc2ac732... 3) how is it related to server_root/reborg js experiments? so I'll try sth more tomorrow or in a week-time On Sat, Feb 28, 2009 at 2:18 AM, Andre Roberge <andre.roberge@gmail.com> wrote:

I agree... this was (and still is) just an experiment.

Agreed.
2) and also I'd like to make it convert all actions to javacript code at once then it would be easier to implement turtel_js and graphics in other projects -- easily escaping crunchy :D
That's a good point. However, the idea was to be able to control a turtle from an interpreter, typing one instruction at a time and seeing the result.
As now for asinchronous update, the server and session must be up all the time
2a) then probably time.sleep would be also good to interface directly to js something like http://groups.google.co.in/group/phpguru/browse_thread/thread/8215dcdc2ac732...
3) how is it related to server_root/reborg js experiments?
It's not - at least not for now. The reeborg experiment is an very early prototype of an implementation of rur-ple (http://rur-ple.sourceforge.net) inside Crunchy. You can see a different version live at http://reeborg.world.googlepages.com/reeborg.html André
so I'll try sth more tomorrow or in a week-time

interactivepython.org uses a customized version of Skulpt (www.skulpt.org) to deliver a full-fledged Python interpreter with a Turtle graphics library in the web browser, with no server calls required. This means that you can download one of those webpages, save it to a USB stick, and deploy it in a classroom in a region with no Internet access. Skulpt has tremendous potential for bringing educational Python to the browser ... a student might be working with me to port pythontutor.com to Skulpt in the coming months.

Hi Everyone, The source code for skulpt, and my implementation of xturtle is also available on github at http://github.com/bnmnetp/skulpt. Skulpt is a Javascript implementation of the Python language that runs in the browser. I spent a good chunk of my Sabbatical a couple years ago implementing the turtle code in Javascript and then writing a wrapper to fit it into the Skulpt environment. We, at Luther College, have used the turtle code pretty extensively in the context of our interactive textbook (http://interactivepython.org) for a couple of years now. This fall we have about 25 schools around the world using the book, so I'm starting to think its pretty stable. :-) The turtle module is still missing event processing functions such as onKey, onClick, etc. But I think the vast majority of the functionality is there. If you do find something missing or have feature requests, please let me know. Brad On Wed, Sep 26, 2012 at 4:32 PM, Jurgis Pralgauskis <jurgis.pralgauskis@gmail.com> wrote:
